Angular2 中的 Passport JS 会话数据

标题：使用Passport JS在Angular 2中处理会话数据的全面指南

bash
npm install passport passport-local express-session

javascript
const express = require('express');
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const session = require('express-session');
const app = express();
// 使用本地策略
passport.use(new LocalStrategy(
  (username, password, done) => {
    // 在这里实现自定义的身份验证逻辑
    // 如果验证成功，调用 done(null, user)
    // 如果验证失败，调用 done(null, false, { message: 'Invalid credentials' })
  }
));
// 配置Passport序列化和反序列化用户对象
passport.serializeUser((user, done) => {
  done(null, user.id);
});
passport.deserializeUser((id, done) => {
  // 查询数据库，通过id获取用户信息
  // 调用 done(null, user)
});
// 配置Express使用Passport和Session
app.use(session({ secret: 'your-secret-key', resave: false, saveUninitialized: false }));
app.use(passport.initialize());
app.use(passport.session());

typescript
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable({
  providedIn: 'root',
})
export class AuthService {
  private baseUrl = 'http://your-backend-api-url';
  constructor(private http: HttpClient) {}
  login(username: string, password: string): Observable {
    // 发送登录请求到后端
    return this.http.post(`${this.baseUrl}/login`, { username, password });
  }
  logout(): Observable {
    // 发送注销请求到后端
    return this.http.post(`${this.baseUrl}/logout`, {});
  }
}
